The pictures here are for reference only, they are just to show that we are able to work on watch Dials and are proud to say that we can exceed your expectations.
If you are interested in starting with Watch Dial, please communicate with us to confirm your requirements, the more detailed the better;
What I wrote here is just a reference solution for you to understand, 1, we will do every detail carefully, 2, need a certain amount of time and cost, because of the different requirements, processing and production solution will be changed.
1. Material Preparation
- Material Selection: Choose a brass alloy suitable for machining and finishing, such as C36000 (free machining brass).
- Stock Sizing: Cut the brass stock to a size slightly larger than the final dimensions of the watch dial to allow for machining tolerances.
2. Rough Machining
- Turning (Lathe):
- Secure the brass stock in a lathe.
- Rough out the general shape and dimensions of the watch dial, including the required thickness and diameter.
- Milling (if needed):
- Use a CNC mill to machine any complex features, such as recesses or contour profiles.
3. Fine Machining
- Surface Finishing:
- Use high-speed machining with fine tooling to achieve smooth surfaces. Aim for minimal tool marks to reduce post-machining polishing requirements.
- Feature Machining:
- Drill or mill holes for watch hands, markers, or other features.
- Use small-diameter end mills or micro-drills to maintain precision.
4. Surface Texturing (Sparkle Pattern)
- Method Options:
- Laser Texturing: Use a precision laser engraving machine to create a fine sparkle pattern on the surface.
- Micro-Sandblasting: Use a controlled sandblasting process with fine abrasive media to achieve a subtle sparkle texture.
- Chemical Etching: Apply a resist pattern and etch the brass to create a sparkle effect.
5. Matte Black Coating
- Surface Preparation:
- Thoroughly clean the watch dial to remove any oils, debris, or oxidation.
- Apply a fine abrasive blast to slightly roughen the surface for better coating adhesion.
- Coating Application:
- Apply a black PVD (Physical Vapor Deposition) coating or a matte black electroplating process for durability and aesthetic appeal.
- Alternative: Use a high-quality matte black paint or lacquer suitable for brass surfaces.
- Curing: Bake the coating as per the manufacturer’s instructions to ensure durability.
6. Final Finishing
- Inspection:
- Check the dimensions and surface quality using a micrometer, calipers, and visual inspection.
- Polishing (Optional):
- If the matte finish and sparkle pattern are uneven, lightly polish specific areas using soft pads while preserving the matte look.
- Deburring:
- Remove any sharp edges or burrs from machining.
7. Quality Control
- Test the final product for:
- Dimensional accuracy.
- Uniformity of the sparkle pattern.
- Adhesion and durability of the matte black coating.
- Surface finish consistency.
8. Packaging and Storage
- Store the finished watch dials in a clean, dry environment to prevent scratches or oxidation before assembly.
